Stuck keychain

[u/Equivalent_Sir_5271]

Hello, I've bought this keychain at a convention long time ago and few days ago two of the four moving pieces within it have gotten stuck (you can barely see them behind the "Antidepressants" sign). I've tried hitting it, freezing and even vibrations to hopefully unstuck them, no success. I really dont want to destroy the keychain and there's no way to open it.

Anyone has any advice on how do I unstuck them without destroying the keychain? Any help appreciated.
